COLLAPSIBLE TUBE.

Application filed A ril 17, 1925. Serial No. 23,849.

To all whom it may concern: 7

Be it known that I, WILLIAM (J. HUN'rooN. Jr., a citizen of the UnitedStates, residing at East Greenwich, in the county of- Kent and State ofRhode Island, have invented new and useful Imprm-ements in CollapsibleTubes, of which the following is a speci fication.

This'invention relates to certain new'and useful improvements in captivetops for collapsible tubes, and the primary object thereof is to providenovel means for enabling positive anchoring of the means which hingedlyand rotatably connects the cap to the tube, so as toprevent bodilyrotation of such means during screwing and unscrewing of the cap inmoving the latter to closed and open positions.

A further object of the invention is to provide anchoring means whichenables the" hinging means to be located at any desired point about theneck, and then firmly secured in the selected position.

The invention still further aims to provide means of the characterdescribed which is of simple and economical construction, and whichenables the cap holding means to be easily and quickly applied andeffectually anchored in the selected position.

In the drawings Figure 1 is a fragmentary side elevation of "a tubeshowing the present invention applied thereto;

Figure 2 1s a top plan view; and 'F1gure 3 1s a rear elevation.

In proceeding in accordance with the pres' ent' invention, the tube body1, is shown provided with the usual base or skirt 2, that flaresdownwardly from the neck proper 3, the mouth of the neck being closedexcepting as to an elongated slot 4, which extends diametrically acrossthe mouth. A collar 5 is formedon the neck and disposed in spacedrelation to and above the top of the skirt 2, to form a groove 6.

The means for hingedly and rotatably connecting the cap 7, to the tube,consists of a piece of wire formed intermediate its ends with a straightbar 8, and having its ends 10 engaged about the neck and disposed in thegroove 6,, in embracing relation v to the neck. The bar 8, afiords apivotal mounting for the attaching means of the cap, as avill now bedescribed.

The cap 7 is provided with a flared collar 11 providing a circulargroove12, in conjunction with the under face of the head of the top. A secondpiece of wire is employed, .which is bent intermediate its ends to forma series of coils 13, which receive the straight bar 8 therethrough andtend to tension the wire upon the bar 8 while the ends 14, of the wireare disposed about the cap and in the groove 12 thereof so as to permitof rotation of the cap in screwing same into and out of engagement withthe threads of the neck of the tube. The wire ends are crossed at 15",soas to cause the wlre ends to more elfectually engage about the cap.

In order to secure or anchor the lirst wire member to the neck of thetube so as to prevent rotation thereof, the ends 10 are disposed inspaced relation, as depicted in Figs. 2 and 3, of the drawings. Themember is then rotated to locate or position same in desired relation tothe usual printedmatter which appears on or is embossedv on the surfaceof the tube 1, following which the collar 0 is depressed between thepoints at 16 the distance existing between l the ends 10, the part 16 ofthe collar approximately equalling the distance between the spaced ends10, whereupon the; part 16-, is bent or forced downwardly so as toprovide an abutment which engages thefends 10', and

holds the wire against rotation-.. It is evident that the whole of thecollar surrounding the tube may be depressed upon the wire if desiredwithout departing from the spirit of the invention.

Due to the fixed holding of the coils 10 on the base of the. neck, thecap is always held in its correct relation to the neck threads whenswung to engage the latter, the cap being held against oscillations atright angles to the tube axis thereby rendering it easier to mesh thecap and neck threads, and also preventing bending of the part 10 ordistortion thereof.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is 1. In combination with a collapsible tubehaving a collar spaced above the neck base, to form a groove, a wire inthe groove having its ends spaced apart and having an intermediatestraight part, 'a cap formed with a circular groove, and a second wirehaving an intermediate part coiled about the straight part of the firstwire and engaged with the. neck base and having 1ts ends crowed andengaged in the groove of the cap in embracing relation thereto, saidcollar of the tube neck having a portion thereof equalling approximatelythe distance between the spaced ends of the first Wire extendeddownwardly to lie in the space between the ends of the first wire so asto engage such ends and hold the first wire against rotation.

2. In combination with a collapsible tube having a collar spaced abovethe neck base, a Wire member having its ends spaced and disposed in thegroove in embracing relation to the neck, said collar having aportiondisposcd in the space between the wire ends to engage the latterand hold the wire member against rotation, a cap, and means rotatablyconnected to the cap and hingedly connected to the Wire member andengaged with the neck base to swingingly and rotatabiy mount the, caprelative to the neck. 3. in combination with a collapsible tube memesand connected to the cap so as to permit the latter to rotate.

l. in combination with a collapsible tube and a cap therefor, a memberengaged about the neck, means to rigidly hold the mem-- ber againstrotation, and means engaging the cap to rotatably mount same and havinga part movably connected to said member and movabl engaged with the baseof the neck so that the latter affords a fixed point about which the vcap mounting means swings.

In testimony whereof I have signed my name to this specification.
